Answer:

B) $26

Explanation:

Marginal Cost Formula:

Marginal Cost = Change in total cost / Change in quantity

Marginal Cost = (2070-1888) / 10-9

Marginal Cost = 182/1

Marginal Cost = $182

Marginal Cost = 182/70 = $26/hour

Working:

9 hours a day

Number of Hours worked during week = 9x7 = 63 hours

Total Cost = ((20+6)x63)+250 = $1,888

10 hours a day

Number of Hours worked during week = 10x7 = 70 hours

Total Cost = ((20+6)x70)+250 = $2,070
